You can then follow up with prompts such as:
- "Preview the data from the 'Project-Management-Sample-Data.xlsx' spreadsheet"
- "Filter the data in the spreadsheet to only show rows from 'Sales' and 'Marketing' projects"

And then import just the data we need from the spreadsheet into the monday.com board:
Import the filtered data from the "Project-Management-Sample-Data.xlsx" spreadsheet into the board
- Only import data for projects "Marketing" and "Sales"
- Add each row with task name as the item name in the group "Tasks".
- Add appropriate columns

- For the "Assigned to" column, just use a text field as those people are not currently in monday.com
- Add a status column and populate the dropdowns based on the percentages in the "Progress" column

The data is imported:
